Still learning the ins & outs of Bluetooth? Or are you a BLE wiz who always appreciates a good primer on the tech? Gene Fabron has written a 101 guide for Tom’s Hardware that talks everything from the stack and manufacturing techniques to the history and partners that move the Bluetooth market forward. It’s a fun read.
In the tenth century, the Viking king Harald Blåtand (Harald Bluetooth in English) united large swathes of modern-day Norway and Denmark under his rule. Fast-forward to 1994, when Ericsson’s R&D teams started investigating ways to connect computers and the “smartphones” of the day without cables. In 1997, Jim Kardach proposed the name “Bluetooth” for the new technology that would unify communications protocols like King Harald had united Scandinavia.
A Bluetooth profile is a set of pre-determined capabilities and a customized stack, determined by the type of operation intended. Profiles make it much easier to design for, implement and manage the very wide variety of Bluetooth operations needed for an application.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
